摘要
研究目的本研究的主要目的是对正颌手术患者使用的正畸托槽、磨牙带和正畸辅助工具的类型和频率进行回顾。次要目的是评估这些项目在正颌手术中的失败风险：这项前瞻性队列研究纳入了荷兰三家医院的 124 名成年患者。五名独立研究人员使用专门制作的数据提取表在手术过程中收集数据。每颗牙齿的手术类型、外科医生、正畸医生以及正畸托槽、磨牙带或辅助工具的类型都被记录在案。为了评估失败风险，还记录了以下变量：失败和部位；失败类型和原因：在接受正颌外科手术的患者中，不锈钢托槽是最常用的托槽类型（75.8%）。24.2%的病例使用陶瓷托槽，且仅用于前牙区域。58.9%的患者使用臼齿托槽带，多数是在第一臼齿上使用托槽带，在第二臼齿上使用粘结管。32.2%的病例出现过一次或多次失败。在所有失败的病例中，三分之一被描述为最后臼齿上的臼齿管脱落。小林结扎法和动力针的失败风险最高（几率比 [OR] 3.70，95% 置信区间 [CI] = 1.91-7.15）。不锈钢托槽、磨牙带环（OR 0.34，95% CI = 0.08-1.43）和陶瓷托槽（OR 0.44，95% CI = 0.14-1.45）的失败率无明显差异：结论：不锈钢托槽、陶瓷托槽、磨牙带和手术钩适用于正颌病例。小林结扎和动力针的失败风险明显较高，因此不推荐用于术中临时上颌固定（TIO-MMF）。
A review and evaluation of orthodontic brackets, molar bands and orthodontic auxiliaries during orthognathic surgery: A prospective cohort study.
Objective: The primary aim of this study was to provide a review of the types and frequency of orthodontic brackets, molar bands and orthodontic auxiliaries used for patients undergoing orthognathic surgery. The secondary aim was to evaluate the risk of failure of these items during orthognathic surgery.
Methods: From three Dutch hospitals, 124 adult patients were included in this prospective cohort study. Five independent researchers collected the data during surgery using a specifically created data extraction form. The type of surgery, surgeon, orthodontist and type of orthodontic bracket, molar band or auxiliary were noted for each tooth. To evaluate their failure risk, the following variables were noted: failure and site; and type and cause of failure.
Results: Stainless-steel brackets were the most frequently (75.8%) used bracket type seen in patients undergoing orthognathic surgery. Ceramic brackets were seen in 24.2% of the cases and were only applied in the anterior region. Molar bands were present in 58.9% of the patients and mostly with bands on the first molars in combination with bonded tubes on the second molars. In 32.2% of all cases, one or more failures were noted. One-third of all failures were described as detachment of the molar tube on the most posterior molar. Kobayashi ligatures and powerpins showed the highest risk of failure (odds ratio [OR] 3.70, 95% confidence interval [CI] = 1.91-7.15). No significant difference in failure rate was found between stainless-steel brackets, molar bands (OR 0.34, 95% CI = 0.08-1.43) and ceramic brackets (OR 0.44, 95% CI = 0.14-1.45).
Conclusion: Stainless-steel brackets, ceramic brackets, molar bands and surgical hooks are suitable for orthognathic cases. Kobayashi ligatures and powerpins had a significantly higher risk of failure so are not recommended for temporary intraoperative maxillomandibular fixation (TIO-MMF).
期刊介绍：
The Journal of Orthodontics has an international circulation, publishing papers from throughout the world. The official journal of the British Orthodontic Society, it aims to publish high quality, evidence-based, clinically orientated or clinically relevant original research papers that will underpin evidence based orthodontic care. It particularly welcomes reports on prospective research into different treatment methods and techniques but also systematic reviews, meta-analyses and studies which will stimulate interest in new developments. Regular features include original papers on clinically relevant topics, clinical case reports, reviews of the orthodontic literature, editorials, book reviews, correspondence and other features of interest to the orthodontic community. The Journal is published in full colour throughout.
